Find second derivation for function f(x)=x²-(2/x)

Vera_Pavlovna [14]

Hi there!

$\large\boxed{f''(x) = 2 - \frac{4}{x^{3}}}$

$f(x) = x^2 - \frac{2}{x}$

Recall the power rule:

$\frac{dy}{dx} x^n = nx^{n-1}$

Rewrite the function for ease of differentiation:

$f(x) =x^2 - 2x^{-1}$

Use the power rule:

$f'(x) = 2x + 2x^{-2}$

Take the derivative once more:

$f''(x) = 2 - 4x^{-3}$

Rewrite:

$f''(x) = 2 - \frac{4}{x^{3}}$

Prove z + z + z + z = 4z. Replace each step with the correct equivalent expression based on the given property or operation. Dra

Olenka [21]

Answer:

Step 1: $z*1+z*1+z*1+z*1=$

Step 2: $z(1+1+1+1)=$

Step 3: $z*4=$

Step 4: $z*4 = 4z$

Step-by-step explanation:

Given

$z+z+z+z = 4z$

Required

Match the steps with equivalent properties

Step 1: Multiplicative Identity Property

This states that:

$x = 1 * x$

So, the expression becomes:

$z*1+z*1+z*1+z*1=$

Step 2: Distributive Property

This states that:

$ab + bc = b(a+c)$

So, the expression becomes

$z*1+z*1+z*1+z*1=$

$z(1+1+1+1)=$

Step 3: Addition

Here, we simply add the expressions in the bracket

$z(1+1+1+1)=$

$z(4) =$

$z*4=$

Step 4: Commutative Property of Multiplication

This states that:

$ab=ba$

So, we have:

$z*4=$

$z*4 = 4*z$

$z*4 = 4z$

Point C has the coordinates (–1, 4) and point D has the coordinates (2, 0). What is the distance between points C and D? d = Sta

34kurt

Answer:

5 units

Step-by-step explanation:

We can use the formula for finding the length or magnitude of line joining two points.

Length = √((x2-x1)² + (y2-y1)²)

The points joining the line are C (-1,4) and D (2,0)

Length = √((2+1)² + (0-4)²)

= √((3²) + (-4)²)

= √ (9+16)

= √25

= 5 units
